Lawmaker Chu Hoi-dick led a small protest outside the UK's Home Office in London on Monday. He wants to find out whether the new Legco president, Andrew Leung, is breaking the Basic Law by holding the post.
Chu says he has doubts about Leung's claim that he has given up his British nationality. Chu says Leung's application was handed in less than two weeks, and that it normally takes 40 days for a Hong Kong resident to complete the process.
Leung says he had renounced his British citizenship before being elected to the post of Legco president on October 12. Chu said that if the procedure had already been completed by then, then the British government must have given Leung special treatment in order to help Beijing.
According to the Basic Law, the council's president cannot have right of abode in a foreign country. Leung has produced several documents to back his renunciation claim. But lawmakers want Leung to produce one called a declaration of renunciation.
